SwiftALM is an Application Lifecycle Management enterprise application. It helps in managing IT and Software projects in the Global Delivery Model. The projects can be traditional or agile and can belong to a wide variety of industries. It combines Process Governance, Program/Project Management and Software Life-cycle Management along with other rich set of integrations. It has been successfully deployed at India's top 3 leading Information Technology/Services Companies along with many other multi-national companies. 1. Responsible for the enhancement and maintenance of the most used module of SwiftALM. Carried out the following activities while working in this module:• Developed SOAP based web services using Java Web Services, EJB so that other applications can seamlessly integrate with the EFORM module by securely consuming data in JSON Format. • Developed Planned Effort functionality using JAVA and EJB. In this functionality, the user would be able to see the planned effort of the task in the timesheet along with the actual effort that he has filled in. This required integration with the Task Module in the application. .• Changed the design of the EFORM module to increase its performance. 2. Responsible for the LDAP and JMS modules of the product:• Implemented Change requests for various clients and also was responsible for the maintenance of the same. 3. Reports Module:changed the server side implementation of the same to pass data to the UI layer in JSON format. Modularized the entire server side implementation of the reports module.• Developed new web services for two product modules i.e EFORM and task to integrate data between various client's systems and SwiftALM.
